The Dräger Interlock® 7500 is an alcohol ignition interlock device which prevents a person under the influence of alcohol from starting the vehicle.

Safety and Reliability

The Dräger Interlock 7500 is E1-marked and complies with all requirements of the European standard EN 50436-2.

The electrochemical sensor of the Interlock 7500 specifically measures alcohol, which ensures that other exhaled substances do not distort the measurement results. This precise sensor technology is also used in breath alcohol measuring devices used by the police.

Operation and Design

Operation is supported by a large display and is simple and intuitive. The mouthpiece is attached to the back of the handset, so it is not immediately recognisable as alcohol ignition interlock. The mouthpiece can easily be replaced, and is hygienic and biodegradable.

Data Storage and Protection

The device stores all relevant data in the control unit. Data can be downloaded via an infrared interface for analysis. The data is protected with special encryption methods.

The benefits of the Dräger Interlock 7500 are not only for the users; for monitoring agents, the 7000 can come equipped with D-SyncTM, a mobile data transfer module that, when enabled, synchronises new data with D-SafeTM, Dräger’s data management system. This technology makes it possible to receive notification of a violation in real-time, as it occurs. Each agency can customise the events that trigger these reports and access the data on-demand.

Sober Driver Verification System

The Interlock 7500 goes one step further to ensure that a sober driver is behind the wheel. An intelligent camera module can detect a change in the driver of the vehicle. When a change is detected, the device will require a breath sample to confirm sobriety.

You choose 

The Interlock 7500 has add ons that you can pick and choose to suit your needs:

  • GPS – Do you need to know where and when your drivers took the tests?
  • Camera – One of the only possibilities of tampering with an interlock is getting someone else to do the test for you. With the camera feature you will not have this problem – the intelligent camera detects changes in the driver whilst on the road.
  • Text alerts – Know when your driver has passed or failed a test instantly. Receive MMS messages which include an image from the camera when the test was taken.
  • Reports – Have reports downloaded when you need them, wherever you are via the web portal. All data is encrypted for protection.
